Retrieving a number where i texted and called

I bought some tickets off of kijiji in march and they turned out being fake. I am trying to find the phone number in my bill but it is not there and the texts only go back three months. is there anyways i can get my call and text history from march? i need to find this number to report it to the police thank you

Hi Andrew! It will be possible for you to retrieve phone numbers dialed and received via your self-serve account; up to 18 months. Regarding the text messages, you won't be able to do so. Have a great week.

Thank you for the reply but I never called them they called me and I think they used a private number because on my bill where it shows the calls it shows my number on that day. And there is no wway of Koodo having a record of what i texted in March? Not the conversation but the number I texted. I am out $250 and I need that money back
